Telephone set base



The attached drawing FIGURE is a left side, upper face surface, and front end perspective view of a telephone set base showing our new design. The undisclosed rear end surface is substantially similar to the front end surface. The undisclosed right side surface is flat, without identation, and is similar in peripheral outline to the left side. The bottom surface is flat, unbroken and is substantially parallel to the rearward plane of the upper surface as shown in the drawing. 

The ornamental design for a telephone set base, substantially as shown and described.
